MODEL PEMBELAJARAN DISCOVERY LEARNING BERBANTUAN GEOGEBRA UNTUK MENINGKATKAN PEMAHAMAN KONSEP MATEMATIS PESERTA DIDIK KELAS VIII MTSN 1 KOTA PADANG

Abstract

Students need to be able to understand mathematical ideas in order to reach certain learning objectives. But the truth is that eighth graders at MTsN 1 Kota Padang still have a long way to go before they can grasp complex mathematical ideas. This is due, in part, to the fact that students are not actively involved in the discovery and construction of the concepts being studied because the learning process is still centred around the teacher. This study's overarching goal is to find out how eighth graders' grasp of statistical mathematics improved after using the Geogebra-assisted discovery learning methodology. Class VIII-1 was used as the experimental class and Class VIII-2 as the control class in this quantitative study that used a quasi-experimental design of the non-equivalent posttest-only control group type. Two tests, one preliminary and one final, made up the research instruments. The experimental class's average quiz scores varied during the discovery learning model's deployment, from 84.72 on the first quiz to 93.23 on the sixth. Another interesting finding from the final test was that the experimental class had a significantly higher average score (73.31 vs. 55.63 for the control class). The hypothesis test results showed that compared to pupils who learnt using traditional methods, those whose lessons included the GeoGebra-assisted Discovery Learning model had stronger grasps of mathematical concepts. Consequently, eighth graders at MTsN 1 Kota Padang improved their ability to understand mathematical concepts as a result of the 2025/2026 statistics curriculum's use of the GeoGebra-assisted Discovery Learning approach.
